Lesson 1: OFDM

OFDM is well used in digital communication. Let us examine it on example. Let's say we have many signals to transmit at the same time. Can we create one signal combined from all the signals we want to transmit intelligently. Yes we can. We create and transmit this composed signal. The receiver can decompose and separate it into signals we have initially. That is it in a nutshell. Now, let's do it. I have the following signals to transmit.

s1 = [ 1 0 1 0 1 0 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ] s2 = [ 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ] s3 = [ 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ] s4 = [ 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ]
